Title:
SURFACE PROTECTIVE FILM
Document Type and Number:
WIPO Patent Application WO/2010/029773
Kind Code:
A1
Abstract:
An adhesive composition characterized by containing a polymer (i), which is a copolymer having a structure represented by the following general formula: [A-B]n (wherein n = 1-3) or a hydrogenated product thereof, and a polymer (ii), which is a copolymer having a structure represented by the following general formula: A-B-A or the following general formula: (A-B)x-Y (wherein x ≥ 1 and Y represents a residue of a coupling agent) or a hydrogenated product thereof. The adhesive composition is also characterized in that the total aromatic alkenyl compound unit content in the polymers (i) and (ii) is 30-50 wt%, and the weight ratio between the total amount of A and the total amount of B contained in the polymers (i) and (ii) is within the range of from 5:95 to 25:75. (In this connection, A represents a polymer block mainly composed of aromatic alkenyl compound units, and B represents a polymer block which is an aromatic alkenyl-conjugated diene random copolymer block having an aromatic alkenyl compound unit content of 10-35 wt%.)
